.. DA9271.005 13 July 2006 MAS9271 IC FOR 10.00 - 40.00 MHz PXO - - - - - - - DESCRIPTION The MAS9271 is an integrated circuit well suited to make initial offset trimming of the crystal in oscillator. The trimming is done by a serial bus and the calibration information is stored in an internal PROM. To build a Precision Crystal Oscillator (PXO) only one additional ponent, a crystal is needed. Low Power Wide Supply Voltage Range CMOS (Square Wave) Output Very High Level of Integration Electrically Trimmable Very Low Phase Noise Low Cost Features - - - - - Very small size Minimum current draw Wide operating temperature range Phase noise <-130 dBc/Hz at 1 kHz offset Square wave output APPLICATIONS - - - PXO for data terminals PXO for telemunication applications PXO for puter application BLOCK DIAGRAM PD MAS9271 OUT DA CLK PV VDD Digital 3 5 VSS X1 X'Tal X2 1 (5) DA9271.005 13 July 2006...
